I'm skeptical. I want to believe it. I want Trump to lose but if you look at the polls from 2016, this company had Hillary Clinton up by 6 with 1 week to go before the election.
I don't think Biden is going to take this state for granted as Hillary did. He knows this state will be tough and looks to be Ground Zero to win the election.
Just cause he doesn't take the state for granted means nothing. Biden like Hillary is a ridiculously flawed candidate who will be toxic among WWC voters based on his positions on TPP, NAFTA, globalization and his Iraq war vote. Biden literally is the swamp. Indisputable.
Your arrogance is astounding.
"Indisputable"? This simply isn't true; Biden stirs up nowhere
near the visceral dislike that Hillary did among some voters. If you don't see this, you're being willfully blind. (And yes, I personally know some union WWC voters in Wisconsin who are examples of this; they voted for Johnson in 2016 because they couldn't stomach Hillary, but will happily vote for Biden).
You claim that every poll that goes against your intuition is wrong. You pronounce with certainty that Trump will definitely win the election overall, Michigan (despite consistently strong polling for Biden), Wisconsin, and who knows what else. Why should we trust your clearly biased "inutition" over gold-standard pollsters like Marquette?
You should try a little humility instead of certainty, and maybe people would take you more seriously and pleasantly instead of dismissing you as an obnoxious jerk.
